structure-activity relationships (SAR) for a novel dipeptide series inhibitors are reported. These inhibitors retain the Phe8-His9 portion of angiotensinogen and employ a unique Leu10-Val11 replacement [(LVR), ref 2]. SAR at the Leu10 side chain revealed that the LVR derived from cyclohexylalanine provided a nearly 10-fold boost in potency for the final inhibitor. In addition SAR work was carried out to delineate the
报道了新型二肽系列抑制剂的进一步的构效关系(SAR)。这些抑制剂保留了血管紧张素原的Phe8-His9部分,并采用独特的Leu10-Val11替代[[LVR),参考文献2]。Leu10侧链的SAR显示,衍生自环己基丙氨酸的LVR对最终抑制剂的效力提高了近10倍。另外,进行了SAR工作以描述结合力与(1)His9位侧链的大小,形状和电荷之间的关系。(2)Phe8位点侧链的大小和拓扑;(3)Phe8N-保护基的大小。当静脉给药时,一种更有效的抑制剂12被证明在钠缺乏的猴子模型中提供了显着的降压作用。在Sprague-Dawley大鼠中进行代谢工作,
